Finally! Nathalie Portman's baby's name out in the open.

Benjamin Millepied and Natalie Portman.

It's out! Benjamin Millepied and Natalie Portman have named their baby boy Aleph. A unique name, that is for everyone that doesn't know Hebrew. Aleph, also spelled Alef, is the (name of the) first letter of the Hebrew alphabet. Therefore it also has a connotation of being 'number one'.

It also has an esoteric meaning in the Judaic Kabbalah, in the theological treaty Sefer-ha-Bahir Aleph relates to the origin of the universe, saying that it's the "primordial one that contains all numbers."
